Problems solved by technology

[0013] (1) The original indoor distribution system involves changes, and an RFID tag system needs to be added
[0014] (2) Only the antenna feeder failure of the indoor distribution system can be monitored, but the source failure of the indoor distribution system cannot be monitored
[0015] (3) It is only suitable for ceiling antennas or omnidirectional antennas, and does not support leaky cables, so the existing methods are not suitable for indoor distribution systems that require a large number of leaky cables, such as subways and railway tunnels

Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] MR (Measurement Report) is a measurement report, which is a measurement report reported by the user terminal to the network during the execution of services, and can reflect the real situation of the current wireless environment of the user terminal. The reporting period of the periodic MR is generally set to 5 seconds. Based on this, the present invention utilizes the collected MR original files to realize real-time and precise positioning of the fault area of ​​the subway indoor distribution system, thereby improving user perception and operation efficiency. The fault location method and system of the subway indoor distribution system provided by the present invention do not rely on third-party RFID tag information, can avoid making any changes to the original indoor distribution system, and can monitor the antenna feeder and...

Abstract

The invention discloses a method for locating a failure of a subway indoor distribution system. The method includes the steps that S1, a subway is subjected to geographical rasterization processing along a line; S2, a position fingerprint database of one-to-one mapping between geographical rasters and signal features of the indoor distribution system is established; S3, MR records reported periodically by a user terminal are collected and matched with the position fingerprint database; S4, the number of the matched MR records in the geographical rasters is counted; S5, according to the geographical rasters, the geographical position of the failure of the subway indoor distribution system is located. The invention further discloses a system for locating the failure of the subway indoor distribution system. Through measurement, a covering level feature fingerprint of each geographical raster in the subway is obtained to realize synchronous generation and mapping of the geographical rasters and the position fingerprint database, MR original files with the minimum time granularity are collected to realize relative and real-time localization for the failure of the subway indoor distribution system, and the failure of the subway indoor distribution system is accurately located.

Description

technical field [0001] The invention relates to the field of mobile communication indoor distribution systems, in particular to a fault location method and system for a subway indoor distribution system. Background technique [0002] The subway has become the most common way of public travel in cities, and users often use the mobile Internet to fill their travel time. Therefore, it is becoming more and more important to ensure the perception of subway users. However, at present, faults in the indoor distribution system of subways are mainly found through "passive response" to customer complaints, which has a large lag, and the fault location is cumbersome, heavy workload, and low positioning accuracy. [0003] The indoor distribution system of mobile communication is mainly composed of active equipment and passive distribution system. The passive distribution system is composed of feeders, passive devices and antennas to realize the transmission and coverage of radio frequen...
